std::inplace_vector<T,N>::clear
From cppreference.com
constexpr void clear() noexcept;
|
(since C++26) | |
Erases all elements from the container. After this call, size() returns zero.
Invalidates any references, pointers, and iterators referring to contained elements. Any past-the-end iterators are also invalidated.
Complexity
Linear in the size of the container, i.e., the number of elements.
Example
Run this code
#include <iostream>
#include <string_view>
#include <inplace_vector>
void print_info(std::string_view rem, const std::inplace_vector<int, 3>& v)
{
std::cout << rem << "{ ";
for (const auto& value : v)
std::cout << value << ' ';
std::cout << "}\n";
std::cout << "Size=" << v.size() << '\n';
}
int main()
{
std::inplace_vector<int, 3> container{1, 2, 3};
print_info("Before clear: ", container);
container.clear();
print_info("After clear: ", container);
}
Output:
Before clear: { 1 2 3 }
Size=3
After clear: { }
Size=0
